furnaces installed in dwellings, apartment houses, etc., for burningrubbish, refuse, garbage and the like and has for its object means bywhich a draft is provided for drying and carrying off the odors of thematerial within the furnaceincinerator when the contents are notburning, as well as the furnace air to support combustion.

It further has for its object an arrangement of the direct air passageswhereby the odor from the material within the furnace is prevented fromescaping into the cellar or basement of the building in which theincinerator is installed.

The inventionv consists in the novel fea tures and in thecombinationsand constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawings in which like characters parts in all the views.

Figure 1 is a front elevation of an incinorator embodying my invention.

Figure 2 is a sectional view on line 22, Figure 1.

Figures 3 and 4 are sectional views taken respectively on lines 83, and4-4, Figure 2. This incinerator comprises generally, a body providedwith a combustion chamber, a flue leading therefrom serving both as achimney flue and as a conduit through which rubbish, garbage and otherrefuse is conveyed to the incinerator, a direct air passage leading fromthe outside of the incinerator to the combustion chamber thereof, theinlet for such passage being out of line with the outlet thereof intothe combustion chamber and preferably below the outlet.

The air intake from the outside of the combustion chamber is open at alltimes permitting a continuous air circulation for drying, burning, orcarrying off of odors.

1 designates the body which is usually formed of brick.

2 is the combustion chamber.

3 is the flue leading therefrom.

4 is the grate and 5 .is the ash pit below the grate. i v

. Aidoor leads into the flue orchimneyat.

built into=one of the walls of the body 1; and arranged to'open into thecombustion chamber beneath -the overhanging wall 8 of the top ofthe'body 1.

The direct passages are here shown as 1 Ashere shown, one of the wallsis formed I double providing an upright passage 9 having. a plurality ofvertical slots or outlets 1O opening into the combustion chamber 2 andalso having inlets 11 opening into the outer air near the base of thebodyl or beneath the combustion chamber or the level of the grate 4.

each floor of the building, through which the rubbish, garbage, etc., isdeposited in the flue.

In operation, the rubbish is usually thrown into the chimneyj3 from thevarious floors or of course, it may be inserted throughthe door ,6; Atintervals, it is ignited. Before the rubbish is ignited, ample air draftis provided through the chimney and the direct air passages and hence,the material isdried and odors from the material are carried 0E nd thereis no liability of the odors escaping down through the direct passagesand the inle'ts ll below the leveliof thegrate 4, owing to the fact thatample draft is provided for. When the material in the combustion chamberis ignited and burning, the draft through the direct passages is ampleto support combustion, it being understood that oftentimes on account ofthe" quantity of the material on the grate, air can not pass through thegrate. Also, while the material is lying on thegrate, but not burning,the positive draft through the direct air passages drives out themoisture from such material and prepares it for burning.

What I claim is: I

1. In a garbage incinerator, the combination of a body formed with acumbustion chamber and an ash pit, a flue leading from the chamber, thebody being formed with a permanently open upright passage in one of itsside walls and with outlet' passages opening from the first passagelaterally into the combustion chamber and with other passages openingthrough the outer wall of the body serving as an inlet to the air, thelatter passages being located below the outlets into the combustionchamber, allof said passageshaving no direct communication with the ashpit. r

2. A garbage incinerator comprising a body provided with argrate, acombustion chamber above the grate, an ash pit below the grate and acombined smoke flue and inlet for the materialto be consumed leadingfrom the top of the body, ,the'top also providing an overhanging wall,permanently open air passages leading from the atmosphere outside of thebody and having outlets opening directly into the combustion chamberabove the grate under the overhanging wall to supply air to supportcombustion, said passages having no direct communication with the ashpit.

3; A garbage incinerator comprising a bo'dy'provid'ed with a grate, a'combustion chamber above the grate, an ash pit below the grate and acombined smoke flue and inlet for the material to be consumed leadingfrom'the top of the chamber, the body being formed-with an uprightpassage in one of its side walls and with outlet passages opening fromthe first passage laterally into the combustion chamber, said lateralpassages extending Vertically slightly above the grate to the top of thechamber, the body also having other passages opening through the outerWall of the body serving as aninlet to "the air, the latterpassagesbeinglocated below the outlets in to the combustion chamber, allof said passages having no communication with. the a ash pit.

In testimony whereof, I have hereunto signedmy name at Syracuse, in thecount of Onondaga and State'of New York, this 30th day of June, 1926."
